Hello Does this state a duplicate IP address is detected?

SA

There is an attacker on this network
A suspicious device (IP address: 192.168.178.23) on Network 2 is trying to scan your computer for open network ports.

What do you do?
Enable VPN \v/
Show details \v/

I would look at the router settings, specifically the ARP table for connections to see if a device shows there with that IP address. And, whether its a device already trusted on the network. If its already there, known to the user, and if its bound to a MAC address known to be a trusted device its good. Otherwise. I would disconnect it anyway and reboot the router to see whether it reappears or not.
